Louisiana is ranks 13th among all states and D.C. for “structurally deficient” bridges according to the American Road and Transportation Builders Association. ARTBA says 1,838 of all Louisiana bridges are flawed.
The bridge is ranked on a 9-point scale and considered structurally deficient if it has a rating of 4 or below. Poor conditions, deterioration, and section loss score a bridge a low rating. Rural and local bridges seem to be in the worst shape, according to federal data, and are crossed more than 4.6 million times.
Louisiana received $4.2 billion in the past decade, but only 66 of 1,200 new bridges have undergone major reconstruction. Meanwhile, 1,900 bridges are “functionally obsolete,” meaning they fail to meet design standards.
